looking for one way internet

I live in egypt , i have adsl , here are the prices:
256k = 16.6 $ per month
512k = 33.3$ per month
1mbit = 66.6$ per month
2mbit = 133.3$ per month
All are unlimited bandwidth

So here is what i am looking for :

I need a 1 way satellite connection with unlimited bandwidth with speed up to 2 mbit with best effort (i mean high probability of 2mbit ) but at least 512k guaranteed and im willing to pay maximum of 50$  per month.
I have a big dish so i can even recieve astra signal.

if u have any offer near this price range please post it here or e-mail me at som3aaaa@hotmail.com
